To all whom it may concern.-

Be it known that 1, JOHN G. GOULD, a citi zen of the United States, residing in Chicago, in the county of Cook and State of Illinois, haveinvented a new and usefulImprovement in Nail-Plate Feeders, of which the following is a specification.

This invention is mainly designed to quicken and render easy the changes and adjustments necessary in this class of machines, and the same is fully illustrated in the accompanying drawings, wherein Figure 1 is a partial side elevation and partial vertical section of my improved feeder. Fig. 2 is a plan of the barrel-carrying saddle and its supporting-bracket, showing the manner in which the former is pivoted or journaled upon the latter. Fig. 3 is a plan of the devices for supporting the grippers which actuate the plate-rod. Fig. 4 is a detail side elevation showing the arm through which the same receive the back-and-forth impulses or oscillating movements. Fig. 5 is a partial front elevation.

In said drawings, A represents the stationary knife, and B is a bracket secured thereto by bolts a. This bracket is adjustable upon the block, the bolts a being made to pass through an elongated slot, 72, in the bracket for that purpose. The outer end of this bracket is formed into a long hollow bearing, 0, in which is inserted the longitudinally adjnstable arbor a, somewhat longer than the bearing and secured therein in the desired position by the set-screw d. One end, a, on the arbor c is pointed and inserted in an appropriate recess in one arm of the saddle D, and the other end, 0', is recessed to receive a pointed pivot, E, passing through the arm of said saddle, thus affording two pivotal sup ports upon which said saddle may rock. The pivot E is locked by the jam-nut 6. With this constructiomwhenever any lateral change is necessary in thegposition of the barrel,(which is carried upon said saddle,) it is only necessary to loosen the screw d, slide the arbor along in the bearing 0 until the barrel has reached the desired position,and then retighten screwd.

F is the standard for supporting the barrel, and is adjustably secured to saddle D by the bolt f, the saddle being also provided with a two projections, g g, entering the same vertical slot, h, in the standard through which bolt f passes. The standard is kept by these pro jections g from turning upon the attachingbolt.

The barrel bearing or cylinder G is pivotally secured to the standard at t, and is rotated in the manner shown by me in a prior pending application by the rack H. A feature of the barrel J which peculiarly adapts it to use in the feeding of wide plates for the production of large nails is the letting of the plate ends of the plate-holding springs] into recesses in the hub of the barrel. In this manner I avoid increasing the diameter of the barrel to such a degree as would make it interfere with the knife-block in adapting it to use with wide plates.

The arm K, through the medium of lever L, receives the impulse of the cannwhereby the barrel is tipped to and fro between the cutting operations. This arm is jointed to the standard F in such manner as to be adjustable thereon, and so it can be moved forward or backward, as occasion requires. Thus in Fig. 4 said arm is provided with a horizontal slot, m, permitting the shifting of the arm upon the standard by loosening the attaching-bolt n.

M represents the grippers for actuating the plate-carrying rod. They are pivoted in the usual manner upon pivotsoin the forked piece N, and the latter is secured to the supporting bracket 0 in a novel manner intended to permit very rapid adjustment whenever the direction of the grippers action needs changing without stopping the machine or loosening the pivot.

P is a vertical pivot passing through both bracket and yoke, and p p are horizontal setscrews bearing against the vertical side of the fork N and located one at either side of the bracket, which may have lateral arms, R, to afford seats for said screws. By turning either of the screws inward and the other outward it is obvious that the grippers will be moved so that they will direct the rod as desired.

I find it beneficial to provide the push-rod S with a slightly-yielding or elastic stop, as distinguished from a positive dead-stop, such as is formed by the knife-block, which has heretofore been utilized for that purpose.

Such an elastic stop is formed by the upright arm'I, attached to a riser, 1, upon the supporting-bracket B.

s is a spring secured to the standard F and bearing against the under surface of bracket 0, and tends to keep the nose of the barrel down upon the knifeblock, and tends to quicken its movements toward that position.

The screw 01 holds the parts which support the barrel in one position during the operation of the machine; but if adjustment is required for larger or smaller barrels, or to regulate the size-of the nail-heads, the set screw is loosened and the feeder moved either way, as required. I 5 I claim-- 1. In a nail-plate feeder, the combination, with the barrel and its supports, of the arm K and connecting-rod L, for tipping the same when said arm is adjustably jointed to said supports, substantially as specified.

v 2. The grippers and their carrying-piece N,

in combination with the supporting-bracket to which said piece is pivoted, and the screws for changing the position of the piece N without stopping the machine or loosening the pivot, substantially as set forth.

3. In combination with the push-rod S of a nail-plate feeder, the slightly-yielding stop T, substantially as set forth.

4. In a nail-plate feeder, the arbor c and c the bearing 0, in which the arbor is adj ustably secured, in combination with the saddle pivotally connected to the arbor at each end of the latter, and the standard F,supp0rted from said saddle, substantially as set forth.

5. The barrel-standard and its arbor c, in combination with bearing 0 and set-screw d, substantially as specified.

JOHN G. GOULD.
